Product Q&A

Q:How to get an exact quotation?

Please send detailed information including Tricone bits (Diameter, IADC code), PDC bits (Matrix or Steel body, blades quantity, cutter size), Hole opener (Diameter, pilot hole size, rock hardness, thread connection), and Roller cutters. Photos are also helpful. Additional info like drilling depth, rock hardness, rig capacity, application type, Incoterm, and port of destination will ensure a more accurate quote.

Q:What are the lead time and payment terms?

Regular models are available in stock for prompt delivery. Mass production lead time depends on order quantity. We accept payment terms including L/C, T/T, D/P, and PayPal. Peak and off-peak season lead times are both within 15 workdays.

Q:Where is the factory located and how is shipping handled?

The factory is located in Hebei, China, near Beijing airport and Tianjin seaport. Transportation to these ports takes only one day, ensuring fast and economical inland charges.

Q:What are the recommended drilling parameters for different formations?

Parameters vary by IADC code. For example, code 117 (very soft formation) uses 0.30-0.753 WOB and 180-60 RPM, while code 637 (hard to very hard formation) uses 0.5-1.2 WOB and 80-40 RPM. Upper limits of WOB and RPM should not be used simultaneously.

Q:What materials are used in the drill bit?

The bit is made of High Carbon Steel with tungsten carbide inserts and inlaid friction-reducing alloy. Thrust faces are hardfaced with wear-resistant alloy.
